Instructions
The following functions can be used with CS/CJ-series CPU Units with unit
version 4.0 or later, or CJ2-series CPU Units.
TXD_SCU(< Send_string >,
< SCU_unit_number >,
< Serial_port >,< Internal_
logic_port >)
Send_string STRING --- Sends a text string to a
serial port on a Serial
Communications Unit. TXD_SCU(a,b,c,d)
(*text string a is sent from
the serial port specified by
variable
c on the Serial
Communications Unit speci-
fied by variable
b using the
internal logic port specified
by variable
d *. The variable
d indicates the internal logic
port number.)

Storage_
location STRING --- Receives a text string
from the serial port on
a Serial Communica-
tions Board. RXD_SCB(a,b,c)
